The spiny, egg-laying mammal that digs into ant and termite nests and carries an electric sense in its snout.
Siamese Fighting Fish
A fish up to 6.5 cm long that breathes air through a labyrinth organ, and whose males flare their gill covers at each other.

The armored desert lizard that turns its own eyes into blood-squirting weapons against predators.
